Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 156-56-9 7GB7U7M282 Hypoglycin Hypoglycine A Cyclopropanepropanoic acid, alpha-amino-2-methylene- (9CI) Cyclopropanepropionic acid, alpha-amino-2-methylene-, L-(+)- alpha-Amino-2-methylenecyclopropanepropanoic acid alpha-Aminomethylenecyclopropanepropionic acid L-alpha-Amino-beta-methylenecyclopropanepropionic acid alpha-Amino-2-methylenecyclopropanepropionic acid alpha-Amino-beta-(2-methylenecyclopropyl)propionic acid 2-Amino-4,5-methylenehex-5-enoic acid Cyclopropanealanine, 2-methylene- Cyclopropanealanine, 2-methylene, L- Cyclopropanepropanoic acid, alpha-amino-2-methylene- HSDB 3496 Hypoglycin A Hypoglycine 2-Methylenecyclopropanealanine 2-Methylenecyclopropanylalanine beta-(Methylenecyclopropyl)alanine beta-(Methylenecyclopropyl)alanine (VAN) NSC 303803 UNII-7GB7U7M282 is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
